problem with Zonealarm and WS-FTP |
|
|
Since I switched to Zonealarm I have a problem with using WS-FTP. When
I start ws-ftp. zonealarm pops up (as normal) ask asks permission for
it, I click Allow, ws-ftp connects and the log window shows everything
normal until the end - logs in, thru "PORT command successful" - the
last command is a retrieve of directory listing, which fails.
If i disable Zonealarm then ws-ftp works fine.
Anyone know what to do? |

Try setting WS FTP to use "passive" mode and see if that solves it....
FTP is an old protocol and is notorious for not playing well with
firewalls. FTP actually runs on 2 ports, port 21 (ftp) controlls
authenticating with the server, but then port 20 (ftp-data) is the port
which hanldes the actual transfer of data. For you, it looks like ftp is
getting though and ftp-data is not. Passive mode utilizes a dynamic port
for the ftp-data connection instead of only port 20 ("active" mode) and
sometimes works better.
Best solution is to dump ftp and use more modern protocols like sftp or
scp, but if your ISP or provider doesn't offer it, you are stuck with
ftp. You should at least ask if sftp/scp/ssh is supported, and if it is,
that is far more reliable and secure. A great free sftp/scp client is
winscp: http://winscp.sourceforge.net.
